Steve anyone help

Steve,
these are all basically the same. Here's #5. It should help you on the others:
3(x4) = 5(x2)
expand to remove parentheses:
3x12 = 5x+10
collect the x stuff on one side:
2x = 22
divide by the coefficient of x: 2
x = 11
finally, check your answer!
3(114) = 5(11+2)
3(15) = 5(9)
45 = 45
if you get stuck on the others, come on back and show how far you got.
